Thanks!
I am thinking of doing something like this:
class Article {
HashSet<Key> reviewers;
HashSet<String> tags;
int status; // pending, approved, declined - derived from reviewers'
statuses
HashMap<Key, Review> mapping; // Reviewer key to Review mapping to prevent
storing making another 1:n relationship
class Review {
int status; // pending, approved, declined
String notes;
... // anything else
}
}
Do you think this will work? It doesn't get me all the things I want, but is
still good enough I think (its kind of sad that we can't model this common
scenario effectively/efficiently).
Do you recommend doing this HashMap kind of a hacky thing or just make a new
Entity and a new relationship? Is it worth the saving?
